Cosmic rays and you



Cosmic rays are tiny particles from space. So what do they have to do with climate

change research? And how much do they increase your radiation dose when you fly?

Hear about this and more from Dr Marc Duldig of the Australian Antarctic Division,

at the University of Tasmania on Thursday November 19. 

Dr Duldig is an expert on cosmic rays.

His talk, ‘Particle Astronomy – The Second Window’, is the last in a series of public

lectures held in conjunction with the Australian Institute of Physics to celebrate the

International Year of Astronomy. 

Traditional astronomy relies on light or other electromagnetic radiation, such as

radio waves or X-rays. 

But astronomers can draw on another tool: cosmic rays, which are particles travelling

almost at the speed of light. 

They twist and turn on their way through space, so it’s been tricky working out where

they come from. But at last astronomers are getting a handle on that.

In his talk, Dr Duldig will discuss what cosmic rays are, how they come to travel so

fast and what they are telling us about the universe. He will also share a history about

several Nobel Prizes related to cosmic rays, what they tell us about the Sun and how,

even today, they are still interacting with the Big Bang! 

He’ll also cover some more “down to Earth” uses for cosmic rays, and their effect on

your body.

Dr Duldig will speak from 8pm at the Physics Lecture Theatre 1, Sandy Bay Campus,

University of Tasmania. All are welcome and entry is free. 



Biography

Dr Marc Duldig is widely regarded as a leader in the field of Cosmic Ray modulation

research. He is responsible for cosmic ray observatories in Australia and Antarctica

and is a member of several key international cosmic ray global network

collaborations. Marc is a Senior Principal Research Scientist with the Australian

Antarctic Division where he manages the atmospheric component of the division’s

climate program as well as the cosmic ray observatories. He is Vice President of the

Australian Institute of Physics and a Secretary of the Astronomical Society of

Australia. 


The International Year of Astronomy is coordinated globally by the International

Astronomical Union and endorsed by the United Nations. IYA activities in Australia

are funded with assistance from the Science Connections Program within the

Department of Innovation, Industry, Science and Research.
